Preliminary results from the project were presented to Willana
Lifesciences representatives at a seminar in Manchester on 19 August
2002. These indicated that sonic collars do reduce overall predation
rates and that the sonic collar is more effective than the bell.
This confirms the results of 4 trials carried out by the British
Trust for Ornithology in 1999, and published on this Website, where
the predation rates on birds were cut by two thirds. The complete
experimental details of the RSPB trial will become available at the
end of September 2002.
